Samar da Hydrogen ta Amonia Cracking

Ana amfani da cracker ammonia don samar da iskar gas mai fashewa wanda ya ƙunshi hydrogen ant nitrogen a rabon mole na 3:1.Mai shayarwa yana tsaftace iskar gas daga ragowar ammonia da danshi.Sannan ana amfani da sashin PSA don ware hydrogen daga nitrogen a matsayin na zaɓi.

NH3 yana fitowa daga kwalabe ko daga tankin ammonia.Gas din ammonia yana riga ya yi zafi a cikin na'urar musayar zafi da tururi sannan kuma a fashe a cikin babban rukunin tanderun.Wutar tanderun tana da wutar lantarki.

Rarraba gas ɗin ammonia NH3 yana faruwa a zafin jiki na 800 ° C a gaban mai haɓaka tushen nickel a cikin tanderu mai zafi na lantarki.
2 NH₃ → N₂+ 3 H₂
Ana amfani da mai musayar zafi azaman mai tattalin arziki: yayin da iskar gas mai zafi ke sanyaya, iskar ammonia tana da zafi sosai.

A matsayin zaɓi kuma don rage raɓar iskar gas ɗin da aka samar ta gaba, ana samun mai tsabtace iskar gas na musamman.Yin amfani da fasahar sieve kwayoyin, za a iya rage raɓar iskar gas ɗin da aka samar zuwa -70°C.Rukunin adsorber guda biyu suna aiki a layi daya.Ɗayan yana ɗaukar danshi da ammonia mara fashe daga iskar gas yayin da ɗayan yana zafi don sabuntawa.Ana canza kwararar iskar gas akai-akai kuma ta atomatik.

Ana amfani da naúrar PSA don cire nitrogen don haka tsarkake hydrogen, idan an buƙata.Wannan ya dogara ne akan tsarin jiki wanda ke yin amfani da nau'ikan nau'ikan tallan gas daban-daban don raba hydrogen daga nitrogen.Galibi ana tura gadaje da yawa don gane ci gaba da aiki.

Tsatsawar iskar gas: 10 ~ 250 Nm3/h
Yawan hydrogen: 5 ~ 150 Nm3/h
